• A high place for viewing objects positioned at a lower level (e.g., a climber, a tree house, a hill, a mountain, a tall building, etc.)
• A toy such as a stuffed animal
• Binoculars (optional)
  

Safety: Use caution when climbing high places.

Find a high place to climb and place the small toy at the bottom of this place, where it will be visible from above.  Compare the size of the toy to something that you will have with you when you climb to the top (e.g., is it as big as your hand, is it smaller than your shoe, is it the same size as the binoculars, etc.?).

Climb to the high place and look down at the toy.  Does it seem as big?  How does it compare to the object you compared it with before your climb?  Can you see all of the toy or just the top of it?

Try looking at the object with the binoculars.  How does the object look now?  Look at other objects with and without the binoculars.  Do they look different when looking through the binoculars?

When we view objects found in the world from a distance, the objects appear smaller than they actually are.

When we see any object, light from the object enters the eye and an inverted image is projected onto the back of the eye. 

When an object is far away, the light from the object is projected at such a large angle that it causes the object to appear smaller.  Likewise, when an object is close, the light from the object is projected at a small angle and the image appears larger.

Binoculars are like two side-by-side telescopes.  Light from the object being viewed is gathered into special lenses that reflect and magnify the image.
